Special Issue Information

Dear Colleagues,

We cordially invite you to submit your original research or literature review papers to this Special Issue on the “Operation of Smart Grids and Microgrids; Methods, Strategies, Optimization, and Challenges” in Sustainability.

The terms ‘smart grid’ and ‘microgrids’ refer to the modernization of electrical networks and consist of the integration of various technologies such as distributed generation, energy storage devices’ dispatchable loads, control and communication systems; operating in different modes of grid-connecting and islanding. Additionlly, the decarbonization of the different energy systems results in a deep transformation applying to the design—and redesign—of the most fundamental structures of power systems and entering renewable energy resources. The traditional operation strategies in these new power systems have been significantly influenced during recent years.

These issues call for the application of different strategies, methods, and tools to tackle the main challenges and arising concepts in the field of operation and control of smart grids and microgrids.

This Special Issue is dedicated to the application of advanced optimization manners and methods to the operation and control of smart grids, and microgrids, focusing on renewable energy resources, managing and decision-making regarding the operational issues in the presence of different uncertainties by wind power plants, photovoltaic systems, and electric vehicles; as well as different strategies and applications such as energy storages, demand responses, combined power and heat aspects, and the other resources/strategies applied to the integration of renewables and increasing their flexibility. Furthermore, the application of different energy carriers in these new systems is of great importance.

Points of interest include, but are not limited to:

  • Uncertainty modeling and decision-making;
  • Optimal power flow;
  • Optimal power and gas flow;
  • Combined heat and power economic/emission dispatch problem;
  • Optimal energy management;
  • Electric vehicle management;
  • Energy storage strategies and devices;
  • Optimization algorithms;
  • Control strategies;
  • Hybrid (AC/DC) power networks;
  • Multi-energy carrier operation;
  • Demand response programs.

With the accelerated development of smart cities, the construction and development of smart grids have an increasing impact on the safe and stable operation of power systems. The benefit evaluation of smart grids can find out the problems of smart grids more comprehensively, which is of great practical significance for the further development of smart cities. In order to ensure accuracy and real-time evaluation, this paper proposes a new hybrid intelligent evaluation model using an improved technique for order preference by similarity to an ideal solution (TOPSIS) and long–short-term memory (LSTM) optimized by a modified sparrow search algorithm (MSSA). First, a set of smart grid benefit evaluation index systems is established in the context of considering smart city development. Then, aiming at the reverse order problem existing in TOPSIS, an improved evaluation model with entropy weight and modified TOPSIS is established. Finally, an intelligent evaluation model based on LSTM with MSSA optimization is designed. The example analysis verifies the accuracy of the model proposed, points out the important factors affecting the benefits of smart grids, and provides a new idea to achieve effective evaluation and rapid prediction, which can help to improve the benefit level of smart grids.

This work tackles a relatively new issue in power system operation, known as the Environmental/Economic Dispatch problem. For this purpose, the combination of two powerful heuristic algorithms, namely, the Exchange Market Algorithm (EMA) and Adaptive Inertia Weight Particle Swarm Optimization (AIWPSO), was employed. Additionally, the Multiple Constraint Ranking (MCR) technique was used to address the system constraints such as prohibited operating zones and ramp rate limits. Furthermore, the mutation operator was used to improve the performance of the global search mechanism. The main purpose of combining these two algorithms was utilizing the EMA’s high performance to explore the global optimum and local exploitation ability of AIWPSO. The algorithm performance was evaluated on six standard benchmark functions and was scrutinized on several different test systems, including 6–40 units. By using the proposed method, the minimum values of the reduction in annual costs, with equal or less emissions, compared to other methods, were USD 17,520, 8760 and 10,801,080, respectively, for the 6-unit, 10-unit, and 40-unit test systems (assuming the same load profile throughout the year). Similarly, in the 14-unit test system for 1750, 2150, and 2650 (MW) load demands, these values were USD 229,879, 148,438, and 4483, respectively. Full article

Microgrids are new concepts in power systems that can upgrade current power systems due to their technical, economic, and environmental advantages. In addition, the increasing penetration of renewable energies and their use in microgrids have increased the complexity of these new grids in terms of planning and operation. Along with numerous research and practical projects built in different countries with multiple applications, countless types of research have also been performed relying on different aspects of MGs. In this paper, based on a review of studies and review articles related to MGs, an attempt has been made to evaluate and report the optimal energy management of MGs, based on what is addressed in the literature. In addition, the most critical surveys on various topics of MGs are introduced as a guide for researchers to draw a road map for future works. Full article

The living lab concept is identified as having the potential to provide a platform to test technologies and support energy transition. However, the application of the concept to the energy sector is limited, though emerging. This study undertook a systematic literature review to understand the extent of the application of the living lab concept, with the particular aim of informing the processes to establish such a platform in urban Africa. Using a sample of 35 papers, only 17 papers were related to energy-living labs, while 18 papers were outside the energy field. The scale and contexts of the application of living labs were diverse. However, not all initiatives that defined themselves as living labs were characterised by elements typical of the concept of a living lab. Further, how the stakeholders were identified, and the stakeholder recruitment process in energy living labs was unclear in the sampled studies. A recommendation is to improve transparency in the stakeholder identification, engagement, and recruitment process in energy living labs and to incorporate gendered issues into the setup and management of urban energy living labs.
